7 ATTORNEY FREDERICK DARIJINGTON, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR TO I \VESTINGI'IOUSE ELECTRIC & MANUFACTURING COMPANY. A CORPORA- TION OF PENNSYLVANIA.

To all whom it 71w, concern/.-

Be it known that I, FREDERICK DARLING- TON, a citizen of the United States, and a resie dent of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Radiators,

of which the following is a specification.

My invention relates to radiators, and particularly to such as are em )loyed in connection with transformers an other electrical f translating devices for. the purpose of dissipating the heat that is generated during the operation thereof, and it has for its object to provide simple and exceptionally eflicient means of the character indicated.

The sizes and proportions of electrical transformers and other translating devices depend largely upon the rate at which heat generated thereby may be dissipated, because it is essential to the preservation of the insulating material employed in the construction thereof that the temperature be maintained atless than a certain degree. In order to facilitate the dissipation of heat, electrical translating devices are frequently oil, which is cooled, either by providing large superficial areas for the receptacles, or

by means of systems of coiled tubing in which water is circulated, the latter means being usually employed when it is desired to cause dissipation of the heat at a greater rate than is ossible with the former means. In certaln locations, however, water is either so expensive or unavailable as to render the use of cooling coils impracticable, and I accordingly propose to partially submerge a plura ity of ermetically sealed tubes or other receptacles in the oil or insulating li uid, the tubes containing an easily volatilize liquid,

such asether or alcohol, of approximately the same depth as the insulatingl liquid.

In operation, the heat of e msulating liquid is conveyed to the volatile liquid within the tube .which vaporizes and rises into the unfilled 'rtions of the tubes, carrying with it heat in latent form. The va ors are condensed in the upper portions of t e tubes, the latent heat of evaporation being thus given off, and the condensed vapors in the form of liqg id return to the lower portions of the Specification of Letters Patent. Application filed June 25,1906. Serial No. 323,367.

RADIATOR.

The single figure of the accompanying drawing is a longitudinal sectional view of a transformer that embodies my invention.

Contained within a suitable receptacle 1 is oil or some other suitable insulating liquid 2 in which a transformer 33 is submerged. Irojecting through a cover 4 for the receptacle 1 and into the insulating fluid 2 are a plurality of pipes or tubes 5, the ends of which are hermetically sealed and the submerged lower ends of which are iilled with alcohol, ether or some other suitable liquid that is more readily volatilized than the insulating liquid 1. The volatile liquid absorbs heat from the'insulating liquid and isvolatilized, the heat being converted into the latent form by evaporation of the volatile liquid.

The vapors rise into the upper portions of the tubes, are condensed and return to the lower portions of the tubes in the form of a liquid, the latent heat of evaporation being given up upon condensation.

While the invention has been shown and described as employed in connection with an electrical transformer, it will be readily understood that it may also be employed as a radiator in connection with other devices, and that the structural details and arrangement of the parts may be considerably varied from what has been shown without departing from the spirit of the invention.

. Iclaim as my invention:

1. The combination with a heated liquid, of one or more sealed receptacles that project into the same and contain a liquid that is more-volatile than the aforesaid liquid.

2. The combination with a heated liquid, of one or more sealed receptacles that project into the same and are partially filled with a liquid that is more volatile than the aforethat project thereinto and are partially filled with a volatile liquid.

(i. The combination with a receptacle, an electrical device located therein, and a liquid in which the receptacle is submerged, of one or more sealed receptacles that are partially submerged in the aforesaid liquid and contain another and more volatile liquid.

7. The combination with a receptacle, an electrical device located therein, and a liquid in which the device is submerged, of one or more sealed receptacles that are partially submerged in the aforesaid liquid, and the submerged portions of which contain another and more volatile liquid. i

8. The combination with a heated substance, of one or more sealed receptacles that project into the same and contain a volatile liquid.

In testimony whereof, I have hereunto subscribed my' name this 15th day of June,

' FREDERICK DARLINGTON.
